Palestinian journalists take part in a protest against Facebook decision to block Palestinian news sites' accounts, outside the UNESCO headquarters in Gaza City on Sep. 29, 2016. Editors from two Palestinian news publications based in the occupied West Bank say their Facebook accounts were suspended last week and that no reason was provided, alleging their pages may have been censored because of a recent agreement between the US social media giant and the Israeli government aimed at tackling "incitement".
